Thanks for the revival Mullin - I've never seen this topic before and I've been having a good old giggle :)
Forgive the repeat of a blog for anyone who read it but a couple of weeks ago, our assistant instructor took class while our sabunim was on honeymoon and when she shouted the word 'coffeetime' we had to run to the back of the hall, do 10 press ups, run to one side do 10 situps and then 10 squat thrusts on the other before returning to wahetever we were doing at the time...
Near the end of class, getting tired, the shout goes up again. Ran to the back of the hall, went down into pressup position while still moving.... realise floor is slipperier than I thought as my feet just kept going, followed by my hands and I smacked down on the floor face first. I looked like a cartoon character on ice.
My hopes no-one had seen vanished with the sounds of the rest of the class quietly giggling on my right... along with the asst instructor.
